Richard had the shoulder repaired by team medical director Dr. Richard Hawkins in Denver. His arm will remain in a sling for five weeks, after which he can begin rehabilitiation.
Acquired from the Baltimore Orioles for Jack Cust on March 11, Richard is hitting .222 with a home run and three RBI in 19 games. He went on the disabled list on May 1 due to a strained left hamstring.
Richard missed the first four months last season following surgery on the same shoulder.
